Virtual MathsJam 2021 is over!
What a wonderful gathering of people.

Thank you all so much for joining in and making it just so good.


One of the
MathsJam activities
MathsJamJam is traditionally a singalong where we sing popular songs that have been rewritten with mathematical lyrics. This year we’re attempting to recreate this in an online way. We’d love you to join in by submitting your mathematical lyrics to a song and/or by recording yourself singing or playing. All the recordings we get for each song will be combined into one track and the tracks will be played at some point over the MathsJam weekend.

Don’t expect beautifully engineered, perfectly balanced songs. Do expect enthusiastic, collaborative performances that capture the spirit of MathsJamJam as closely as possible given the circumstances. That’s what we’re aiming for, anyway!

Instructions - Short Version

Submit lyrics as soon as you can, with a link to a karaoke/instrumental version of the song, and optionally a guide vocal. Upload here:

Instructions - Long Version


Rewrite the lyrics to a popular song, giving them a mathematical theme. If you need inspiration, look through the MathsJamJam Songbook 2016-2019

to see what other people have written. When you’ve written your lyrics, choose a karaoke or instrumental track for the song. There are plenty available on YouTube, or record your own if you prefer. This will be used to line up recordings, and possibly as a backing track if nobody sends an instrumental recording. Add a link to the track in your lyric sheet and upload the lyric sheet here:

or send by

If you want to, you can record a vocal guide to show how the lyrics fit and for other people to harmonise to. This is completely optional - if you don’t provide one, we’ll try to get somebody else to record one.

There’s no fixed deadline, but the earlier you submit your lyrics, the more time people will have to make recordings.


Choose a song or songs from the lyrics folder:

and record yourself singing and/or playing the song. You can do lead vocals, backing vocals, guitar, tambourine, grand piano - whatever you fancy! Play along to the instrumental or guide vocal track that is linked to on the lyric sheet, so that everyone is playing at the same tempo, but please use headphones to listen to this track - your recording should contain only your performance, otherwise we’ll have multiple layers of the karaoke track on the final version.

You’re welcome to submit more than one recording, and to listen to any recordings that are already in the folder to see what other people have done. Audio or video is fine, we’ll attempt to put together whatever we receive. It doesn’t matter if your performance has mistakes - participation is more important than perfection!

Name the files using this format:

For example:

If you don’t want to be credited on the final version, don’t include your name. Upload your tracks here:

or send them by

Note that the upload folder is public - emailed files won’t be put in this folder, and will only be heard combined with the other recordings, so if you prefer to keep your solo performance private then email it. If the file is too big to email directly then you can email a link to a file on dropbox/google drive etc.

The deadline for recordings is 17th November

It's a soft deadline - we’ll do our best, but we can’t guarantee to include anything received after this date.
